"It's so sad," Morello tells Music Radar. "We had talked about playing more Audioslave shows and releasing that material and doing something together in the not-too-distant future."
Morello says he misses collaborating with Cornell.
"He had a very wonderful and unorthodox songwriting talent. It was sort of part-Beatles, part-Black Sabbath, but he had this internal non-4/4 time signature clock in him that was really interesting, and it's in some of those Audioslave songs where he would contribute chord progressions."
